Schlage ND78JD Ath 626 Classroom Security Cylindrical Lock

Product Description

The SCHLAGE ND78JD ATH 626 is a Grade 1 cylindrical lock designed for classroom security applications requiring 180-degree lockdown capability. Built to ANSI/BHMA Grade 1 standards, it delivers the durability and cycle life demanded in institutional and commercial environments. The lock features the Athens lever trim and ships less core, configured for Schlage Full Size Interchangeable Core (FSIC) prep. The satin chrome finish (626) provides a clean, corrosion-resistant appearance suited to high-traffic facilities. Installation is performed by a licensed locksmith or commercial door hardware technician.

This lock is intended for classroom and educational facility doors where rapid lockdown from inside the room is required. The 180-degree lockdown function allows occupants to secure the door without entering the corridor, meeting the operational needs of school safety protocols. The non-handed design simplifies inventory management and allows installation on doors with either hand without modification. The FSIC prep accepts standard Schlage full-size interchangeable cores, making it compatible with large-scale masterkey and access control programs common in K-12 and higher education facilities.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with ANSI/BHMA cylindrical lock standards. Verify the door prep matches the required cylindrical backset and cross-bore diameter before installation. Because this unit ships less core, a compatible Schlage FSIC core must be sourced and installed separately before the lock is operational. Always confirm local building and life-safety code compliance, including applicable IBC and NFPA 101 egress requirements, before specifying this function for any door.
